LEWIN A. GOLBERT, OF BALTIMORE, MARYLAND.

WARMING APPARATUS.

Specification of Letters Patent No. 30,614, dated November 13, 1860.

T 0 all whom it may concern:

Be it known that I, LEWIN A. COLBERT, of the city of Baltimore, in theState of Maryland, have invented a new and useful improvement inregisters for the purpose of receiving and disbursing warm air intorooms of houses, from every warm air generator; and I do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings and t0 the letters of referencemarked thereon.

My invention relates to a receiving and disbursing warm air reservoirfor parlors and other rooms which require to be heated with warm airfrom a furnace located in a cellar or other low position, and the natureof my improvement consists in the adaptation and the arrangement of awarm air reservoir of box or niche form and furnished with a door, abottom passage, a side dampered passage and a top damper-ed passage, allfor use in combination with the ordinary furnace hot air flue, draft orchimney flue and flue leading into the chambers above, in the manner andfor the purposes hereinafter described.

To enable others skilled in the art, to make and use my invention, Iwill proceed to describe its construction and operations.

First, I construct a receiver A of any suitable metal, and of a box orniche form, such as is made in a wall for statues to stand in, and ofdiscretionary size, with a flat front, with the flange (A) around thefront of box, projecting about one and a half inches or more, and withthe door (B) hung to the same by hinge, and a catch, to keep the door inits place so that the receiver may be closed up tight. Secondly, I havethe collar (C) on the under side of the bottom, of size to fit the warmair pipe, wherein the warm air flows into the receiver through thegrated hole (D). Thirdly, I then place the escape valve (E) on theinside of the back, as near the top as possible, for the warm air, whennot wanted, to make its escape into the chimney or flue, to pass offentirely. Fourthly, I place valve on the inside of the top to let thewarm air go up to next story above, if wanted, which pipe fits on thecollar (G) on the outside of the top, which is to be about the same sizeas the one below;

now closing those two valves on inside of receiver (E and F) and openingthe door (B) you will have all the heat thrown into the room. By closingthe valve (E) and opening valve (F) and closing the door (B) in frontyou will throw the heat into the room above. By closing upper valve (F)and opening the back valve (E) and closing the door (B) you let off thewarm air into the chimney or flue.

I am aware that a warm air closet is not new, but I am not aware of theexistence of a warm air reservoir used in the manner and for the purposeI have described, and provided with a-door for shutting OK the air fromthe room or letting it into the room and with dampers for retaining thehot air while the door is open, or letting it ofi into the chimney orinto rooms above, when the door is closed or when too much hot air hasbeen husbanded. I am also aware that on Plate 68 Figs. 17 and 18 ofPecklets Trait de la Ghaleur the fire place or chimney flue of abuilding is shown converted into a hot air receiver, but as the chamberhas no dampers through which the hot air can pass off through the fluewhen the dampers leading into the apartments are closed it will notanswer the end I have in View, besides this it is very different in itsconstruction and arrangement from my invention. I likewise am aware thatin Websters Encyclopedia of Domestic Economy a hot air closet forwarming dishes is described and illustrated, but this has no dampers forconfining, letting ofi' and distributing the hot air, and is not adaptedfor the purpose 'I have described. I further am aware that T. H. Parkerobtained a patent Aug. 1st, 1848 on a hot air chamber formed in thechimney flue by dividing the flue horizontally with partitions. Thisarrangement however has no dampers or devices for letting off the hotair when it is not wanted in the room or when the wall and chimneybecome intensely heated by the confined hot air; therefore it will notserve the purpose I have in view.

Having thus described my invention and shown wherein it differs from allother things before known, I will state that I do not claim anythingembraced by the several old devices alluded to in my specification, but

What I do claim as my invention and defurnace hot air flue, draft orchimney flue sire to secure by Letters Patent, is and flue leading intoelevated chambers, sub- 10 The adaptation and arrangement of astantially in the manner and for the pur- Warm air reservoir or receiverA of box poses herein set forth. 7
